我正在研究 CANalyzer,但找不到如何调用包含参数的 CAPL 函数。如果我放入num
它functions_call.Call(num)
不起作用。
def call(num):
print 'calling from CAN'
x=int(num)
functions_call.Call()
return 1
不久前我遇到了一个类似的问题,一些谷歌搜索让我看到了 Vector 的以下应用说明:
...结帐部分“2.7 调用 CAPL 函数”。
总而言之,确保将 CAPL 函数的参数声明为“long”,.eg:以下似乎对我有用:
void function1(long l)
{
write("function1() called with %d!", l);
}
为了完整起见,这就是我的 python 代码(对于上面的示例)的样子:
from win32com import client
import pythoncom
import time
function1 = None
canoe_app = None
is_running = False
class EventHandler:
def OnInit(self):
global canoe_app
global function1
function1 = canoe_app.CAPL.GetFunction('function1')
def OnStart(self):
global is_running
is_running = True
canoe_app = client.Dispatch('CANoe.Application')
measurement = canoe_app.Measurement
measurement_events = client.WithEvents(measurement, EventHandler)
measurement.Start()
# The following loop takes care of any pending events and, once, the Measurement
# starts, it will call the CAPL function "function1" 10 times and then exit!
count = 0
while count < 10:
if (is_running):
function1.Call(count)
count += 1
pythoncom.PumpWaitingMessages()
time.sleep(1)
